hi. did you manage to come right with pinout info ?

check the inverter manual if you have one. It differs from brand to brand but most have a screw/bolt on the panel where the wiring is connected.

Had the same issue with my new batteries and the manual specifically says the inverter must be set to 58.4v bulk and float charge voltage. the BMS then has its own settings to monitor and control the battery input and output but it still needs that higher input voltage setting on the inverter. the lithium chemistry batteries charge in 2 stages : CC - constant current and switches over to CV - Constant Voltage . depending on bms voltage and inverter voltage settings if set too low then the battery does not fully charge to capacity. the pic i posted is from the BSL manual that has the recommended settings. https://bslbatt.com/wp-content/uploads/2023/02/PowerLine-OPERATING-INSTRUCTION.pdf https://bslbatt.co.za/wp-content/uploads/2023/03/PowerLine-5-230202.pdf

this is from the manual for the BSL batteries. Charge voltage on inverter should be 58.4v. charge amperage 50amps. as P1000 mentioned. i think the charge voltage is too low at 54.3v.

these i was told are using the Felicity protocol and the pinout corresponded to the manual provided. I used the pinout in the manual to connect with pbms Tools. i connected to and used the RJ11 6 pin plug to serial adaptor. problem is finding the pinout or protocol for the new Fivestar inverters

Themba, No you can not use a 24v battery on a 12v inverter. you will get the magic smoke if you do.

hi can you elaborate on what you did to get it working ?

have you come right ? i am having the same issue. app on phone shows device under datalogger but only when wifi is connected to the dongle . will not connect to my wifi after following prompts in "network setting" device shows up on Dessmonitor but always offline.

most likely depends on how unit is setup. post your hardware model etc and its settings, so guys can assist. without that info its hard to comment.

great info I must check the Sunmagic 48150 51.2V 150AH batteries if it possibly has the same bms. These are also sold as Fivestar units.

this is a good guide and other manuals has good info on the website. https://thesunpays.com/downloads/files/Inverter Settings LiFePO4.REV3.pdf

thanks for the heads up. Not really worthwhile selling it cheaper than R6k. Paid R14k will keep it as a backup/spare.

I was considering getting a 2nd 5kv axpert King inverter to run in parallel but after looking at pricing, additional expense for the wiring etc and to also have the space for a 2nd unit. For similar money i chose to rather go to a larger 15kv unit instead to replace the 5kv. At end of the day its what suits the pocket for most.

try this . Looks similar to this inverter. https://sakopower.com/wp-content/uploads/2022/03/Sunon-pro-Solar-Inverter-User-Manual.pdf
